I'm not sure anymore. There was a time when a Basecamp update and device firmware updates meant that all restrictions were simply ignored. I think newer Basecamp version corrected that bug again however (Garmin claimed on their forums such restrictions never existed - so maybe they really did not use them in their maps?). I'm not sure for the devices though - Got not much time right now - but I can check with my devices in September (Oregon 600, etrex 30 - Vista HCx was never affected by that bug). Toll and Unpaved have never been affected either and are really avoided if set so. On 11 August 2015 at 11:39, Gerd Petermann <gpetermann_muenchen@hotmail.com> wrote:
Hi Felix,
can't believe that Garmin ignores it, can you prove that with the default style? If not I assume that you create multiple arcs and one allows cycling.

okay - sounds great... (as new devices do not really mind mkgmap:bicycle=no it does not matter so much anymore - I'm only setting pedestrian restrictions different to all others for my maps )

Hi Felix,
My current approach is to evaluate the results of the style, so it is up to the author to decide what a pedestrian-only way is. Another point is that we don't need the check for ways which can't be accessed by bike. I am aware that these checks must be ignored when a special cycling map is created (or any other special map, we just have to find out meaningful option names)
I am trying to produce test data to find out in what case Garmin prefers a small detour, this should help to find concrete rules.

Well - what is a strict pedestrian only way? highway=pedestrian - often can be used with bikes too (going slower) highway=footway -- often still outside cities and used for mtbiking though maybe not allowed. highway=path & bicycle=no ---> very often nice mtbike trails in countries where mtbiking is mainly forbidden like Baden-Wuerttemberg or Austria.
And yeah - oneways could be excluded - but needs some care to not exclude them (for cycling maps) if oneway:bicycle=no; bicycle:oneway=no; oneway:bicycle=both; ( cycleway=* & cycleway!=oneway ) would be the most common keys which mean cycling against oneway direction is allowed.
For me excluding all ways that get tagged road-class=0 or 1, and road-speed=0 could be excluded (but sometimes I use continue and double ways so it exists with say road-class=4, road-speed=2 as well as road-class=0, road-speed=0 in order to get me through sharp turns - if the sharp angle fixing would work well - maybe I could drop this).

Hi Felix,
okay, I just try to find some criteria so that we find those nodes + arcs which really cause trouble. A lot of sharp angles are between oneway roads which don't allow traveleling the sharp angle. I think that also means that I can add code to ignore sharp angles on pedestrian-only ways.

Well - not in Pedestrian mode. I meant if you design a map with road-class=4 as preferred way for pedestrians... Then of course using a non pedestrian profile for routing so it chooses road-class=4 or 3 preferably. For Pedestrian mode chosen - there is no time penalty for sharp turns - though I did not test if it would prefer ways that point towards the destination at intersections.

Hi Felix,
please check: you said that sharp angles also have an effect on pedestrian routing, I was not able to reproduce that. Can you give an example?
